# simple

A word boundary algorithm that implements the “simple word boundary” Unicode recommendation.

## Declaration

```swift
static var simple: RegexWordBoundaryKind { get }
```

## Discussion

Discussion A simple word boundary is a position in the input between two characters that match /\w\W/ or /\W\w/, or between the start or end of the input and a \w character. Word boundaries therefore depend on the option- defined behavior of \w.
